Phosphotransacetylase | definition of phosphotransacetylase by Medical dictionary
Also found in: Encyclopedia
an enzyme that catalyzes the transfer of an acetyl group between acetylphosphate and acetylcoenzyme A.

After centrifugation, clear supernatants were taken for acetyl-CoA determinations by the cycling method using phosphotransacetylase
and citrate synthase (23).
This reaction is in contrast to the two-step conversion in anaerobic bacteria whereby acetyl CoA is transformed to acetate via phosphotransacetylase
and acetate kinase:
coli is grown on glucose, acetate is produced from acetyl-CoA by phosphotransacetylase
(pta) and acetate kinase (ackA) from pyruvate by pyruvate oxidase (poxB).
